This makes me smile, when I think of all the things I’ve neglected to bring for various shoots, up to and including… the camera. (but in my defense, only as far as the end of my driveway)
I tend to pack a ton of stuff and so I agree with the idea that “you never know, so all you can.”
But the challenge of this question is to pack as light as possible. And for me, that particular list changes totally, based on the shoot. Another way of looking at this is, when you fly, what do you bring in the carry-on kit rather than checking it, so that you can make a movie even if the checked cases don’t get there on time?
I like all of the lists. Nick’s Flex-Fill is a great one. I think I’ll add that to my basic kit now. My Flex-Fill is kind of big so I don’t “always” have it; a small one is a fantastic idea.
Some more items from my list that I don’t recall from reading the above posts:
Little loops of velcro are super-easy to bring. I just keep them on the straps of my camera bag.
Little case of extra AA batteries.
Lens cloth and brush.
EXTRA CAMERA. It is ridiculous not to pack a tiny HD camera and a way to mount it in some weird location.
This case is getting heavy….
Alternatively, if the shoot allows it, there is something quite bracing about not having all that crap to carry around. Carrying one DSLR camera (with a moderate zoom) can re-open your eyes to the joys of “seeing” rather than just lugging equipment. And you can make an excellent case (no pun intended) that carrying as little as possible enables you to move more quickly, be unobtrusive, and get shots that would be impossible with a large convoy of cases bogging you down.
